Chromosome aberrations in Siberian spruce under different natural conditions of the Southern Urals

Researches the chromosome aberrations in Siberian spruce under different natural conditions on the Southern Urals (high mountains, mountains, foothills, plains, valleys of the rivers, areas of natural geochemical anomalies). The results provide that test plots of species under studied differ in their level and nature of the chromosome aberrations, the highest level of aberrations observed in high mountains and areas of natural geochemical anomalies. Between test plots from extreme and optimal growth conditions established reliability of differences at different significance levels.
